Extensive Roof Substrate

Extensive Roof Substrate

Extensive Roof Gardens are low maintenance (most common concentrated on sedum platning) green roofs designed specifically for environmental purposes.

We use a various grades (2/5mm, 5/10mm and 5/15mm) of crushed brick in our Extensive substrate blends. Since the recent revival of house building (especially int he South-East of the country) recalimed bricks have been harder to come by as brick works have aimed to reduce the amount of wastage. We have always maintainted that crushed brick is the most effective base media for creativng an Extensive roof system due to its dual ability in retaining moisture and maintaining its lightweight element.

We blend to order using either of our grades of crushed brick, along with 10mm PAS100 green compost or composted bark (most commonly used when creating a wildflower area)

We have implemented our Extensive Roof Substrates extensively across the London sky line as well as schemes across the South-East fo the country. Please click on the data sheets on the left of this page for technical information on this and any other of our materials.
